RIB FOR LmTnns nn sins.

" Application filed July23, 1918, Serial No. 246,325.

To all whom it may concern:

Be it known that I, WILLIAM ADRON RAGSDALE, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented a new and useful Rib for Linters and Gins, of which the following is a specification.

This invention relates to ribs for linters and gins, one of its objects being to provide simple and efficient means whereby, as the cotton seeds are drawn along the ribs by the saws, the lint will be rubbed therefrom by an abrasive surface shaped to enga e all portions of the seeds and remove practically all of the lint therefrom.

Another object is to provide a rib the abrasive portion of which can be removed readily and another substituted therefor.

With the foregoing and other objects in view which will appear 'as the description proceeds, theinvention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of part of a rib having the present improvements combined therewith.

Fig. 2 is a longitudinal section through a portion of the structure shown in Fig. 1.

Fig. 3 is a section on line 3-3, Fig. 2.

Fig. 4 is a face view of the abrasive portion of the rib.

Referring to the figures by characters of reference, 1 designates a rib of the usual contour and proportions, the same being provided, at a suitable point thereon with a longitudinal recess 2. This recess can be of any shape desired although preferably of the form shown in Figs. 2 and 3 wherein one end wall of the recess is perpendicular to the adjacent portion of the bottom of the recess, as shown at 3 while the other end wall is inclined as at l and leads to a shallow extension 5 of the recess. The bottom of the Specification of Letters Patent.

recess may be straight from side to side as shown in Fig. 3 and the side walls may diverge outwardly as at 6 for a portion of the height thereof. Fitted within the recess 2 is a block 7 of abrasive material such as carborundum, one end of the block bearing snugly against the wall 3 of the recess while the other end engages the wall l and forms a short nose 8 adapted to be lapped by a retaining plate 9 which is fitted in the recess extension 5 and held in place by a screw 10 or the like. The block 7 is formed with a longitudinal rib 11 having rounded ends and, which gradually increases in width from one end to the other as shown in Fig. i. From an intermediate point, 12, the rib gradually diminishes in thickness toward its ends, as shown in Fig. 2, and throughout its length the rib describes a double ogee curve, the sides of the rib merging into portions 13 which are flush with the adjacent face of the rib 1.

A number of ribs such as described are to be assembled in the linter or gin in the usual manner with the saws working between them. During the operation of the saws the cotton seeds will be rolled between the saws and the ribs, a Wiping action thus being set up resulting in the cotton fiber or lint adhering to the block 7 until pulled from the seed whereupon it will be released, it having been found that carborundum, especially, while constituting an excellent abrasive substance, likewise keeps clear and does not require cleaning. Practically all of the lint will be removed from the seeds by this device and a great saving of time and material is effected over the ordinary methods of removing the lint.

What is claimed is 1. A rib for linters and gins, having an abrasive surface.

2. A rib for linters and gins, abrading element thereon.

3. A rib for linters and gins, having an abrading rib extending longitudinally therealong.

4. A rib for linters and gins, having a transversely rounded rib of abrading material extending therefrom.

5. A rib for linters and gins, having a block of abrading material connected thereto and providing a longitudinal rib.

6. The combination with a rib for linters having an In testimony that I claim the foregoing as my own, I have hereto afiix ny signature 10 in the presence of two Witnesses.

and gins, having a recess therein, of a block of abrading material secured in the recess and projecting from one face of the rib.

7. The combination with a rib for linters and ins, having a recess therein, of a block of a rading material detachably secured therein and having a rib projecting from one face of the recessed rib.
